If you want some actual fixed attenuators:

Yes, electrical interference is greater on VHF. It could also be from multipath reflections coming from other directions because of the simple V antenna. Again from ATSC A/74:



A more directional VHF antenna would reject many of those reflections.

Note from the table that the greater the difference in time between the main signal and the echo (reflection), the weaker the echo must be to not interfere with reception.

How often do you see the uncorrected errors? Once-a-day for a few minutes, or more like almost constantly?

Do you see picture and audio problems on your TV only when you have errors?
Any adventage or disadvantage to using a splitter vs. an attenuator? I'm assuming the 3db attenuator would be the one to get if going that route...
